This is a black panel for the new GPS variant of the King Air 350. It is not compatible with the non-GPS variant as there are already black panels for that version.
Check out my custom interiors as well
1) I want black panel just for one livery - open the folder and place all .png files into King Air 350/Liveries/livery/objects
2) I want it for all liveries - open the folder and place all .png files into King Air 350/objects
